Hermes was one of the ancient Greek gods, and one of the Olympians. He was the god of many things, including trade, travel, messengers, athleticism and thievery. He was the son of Zeus and Maia. Hermes was always causing trouble, even as infant, when he stole Apollo's cattle. Despite his trickster tendencies, he was constantly running errands for the gods, such as when he brought Calypso the order to set Odysseus free. Hermes is often depicted as an athletic man, usually wearing winged sandals or a winged hat and carrying a caduceus. The ancient Romans based their god Mercury off of Hermes.
